To all whomit m'ag concern: Y

Be it known that I, GERALD ALBERT PHILLIPS, a subject'of His Majesty the King ofGreat Britain and Ireland, residing at Beechcote, Berkswell} Coventry, 1n the county of Warwick, lilngland, have invented new and useful Improvementsin Means for' Making Iron Molds for Casting lMetallic Bedsteads and like Articles, of which the following is a specification.

TlllS invention has reference to those ironv molds technically known as chills,vwhich are uses and which are adapted to receive the made in halves or Otherwise in two or more part are used in the manufacture of metallic bedsteads and acts and for other like i ends or other parts Ofgtllbes or bars or other castings or parts andt'o'form inclosed or partly inclo sed molds for the reception of molten cast iron which forms the chilled castings around said tubes, bars or parts to secure them together, as in the case of what are knowx'i as flower chills in a bedstead rail or cot rail, orto form a top or other casting on a pillar, or a corner casting on a pillar rother chill casting where required in the construction of ametallic bedstead or other article of metallic furniture or other chillediron casting. The halves-or parts of themolds mufs't match and fit. accuratelytogether and h'eret'ofore these iron molds or chills have u s ually"b'een made as sand. castings in halves which have been machined Where nec'essary and fitted together. and trimmed up and finished by hand or machine labor-{the said half molds having internallytlie ornamental or other shape 'of the requiredi'cast' part of'the bedstead 'ori other required chilled casting and also hav' 'tion of the tube or tubes or other partspn to which the chilled castingis to be made. These iron molds or chills as'at present made are comparatively expensive as a large num-. ber of them arerequired for every different- Q pattern of mctallicbedstead or cot, and this is particularly the case with flower chills as in the simplest form of bedstead rail made with top and bottom tubes connected together by seven uprights, fourteen pairs of these flower chills all exactly alike are required to form the chilled castings conrnecting theends of the uprighttubes with ,the' horizontals, one half of eachpai'r being wfixed by screws or other means to a frame at ing one or more cross channels for the recep r03. casrme niErALLIc Bnnsrsens Ann LIKE ARTICLES.

the proper distances apart and the other half of each pair being detachably connected to these by being-hinged thereto or by chill hooks or by other suitable means. It follows therefore that a bedstead manufacturer has to keep mzinytons of these iron molds a1- ways in stock whichhave cost a Very considerable sum to produce as every one of them has been fitted together and finished by hand or. machine labor.

. It is well known that in practice those portions of the, iron molds or chills with which the molten iron comes into contact and particularly the edges of the recesses in the meeting faces of the iron molds or 'chills soon become indistinct and incorrect in very materially reduced, they are formed with 'absolutelysharp edges to the recesses of their meeting faces, the cost of their renewal is considerably reduced and moreover the weight of the iron molds or chills which it"will be necessary for a bedstead manufacturer to keep in stock when madeaccording to my invention will. be reduced to a c minimum.

In carrying out this invention those halves or parts of the said hollow iron molds or chills which areliable to wear thm'iigh coming in contact with the molten metal and which chills or parts I call the working chill molds are not made aslsandcastings as heretofore but are made as chilled iron castings in iron molds or chills whichfor distinction I call the master chills and from which any number of the said working chill molds can be made at a very small cost. The a working chill molds are removably fixed in the stocks onthe sto'ck frame in such a way that they can very readily be changed when required; Thus in making for instance a set of say' foi1rt,een pairs of. flower chill molds to., be:iiXedJon a'stcck frame for castinebedstead rails, two master chill molds either sep rately or, in one piece are first .moldsgthe pattern shape or configuration of.

made as sand ..astings, one-i11aster chill for' each C the two working flower chill half these master chill molds corresponding with the halves of the working flower chill molds which are required, and then from these master chill molds which have been carefully finished the necessary number of halves of the Working flower chill molds The working chill half molds are interchangeable so that the same stocks or body.

portions of the molds will serve for holding different patterns of working chill .hal

molds which latter are very inexpensive owing to the very small amount of labor required to produce them. The weight of the iron molds orchills which it will be necessary for a bedstead manufacturer to keep in stock will be represented by the weight of the master chills which will be very small in comparison with the many tons ofiron molds .whiclrb dstead manufacturers have heretofore had to hold.

The figures of-the accompanyin draw ings illustrate by way of example ow my invention is carried out-in connection with the said flower chills for a metallic bedstead rail and they will serve to illustrate also how my'iiivention can be applied to the chilled half or part molds for use in casting other chilled castings in the construction of metallic bedsteads or other articles of metallic furniture or other chilled iron castings.

Referring first of allto Figs. 1, 2, 3, and 4, the two removable and renewable chilled cast iron -working chill half molds are i'especti'vely marked '1 and 2, the working chillhalf mold 1 being recessed on its inner face at 3 to form the front of the required flower chill 4 of the bedstead rail where the vertical tubes 5 of the same meet the horizontal tubes 6 and 7 of the rail, the other:

chill half mold 2 which matches the workingchill half mold 1 has its recessed face 8 shaped to correspond with the back of the flower chill 4. Each of these working flower.

chill half molds also has the necessary groove 9, to receive the vertical tube 5 and grooves 10 to receive the horizontal tube 6. Each of 85 one part of atwo part. sand molding box the said working chill half molds 1, 2, also has, formed in its face a groove 11 along which the metal runs as it is poured into the mold. These working chill half molds 1, 2, are respectively removably fixed in the two half stocks or body portions 12, 1.3, which are sand castings jointed together at one-side by a joint pin ll passing through knuckle lugs 15, 16, formed respectively onthe two half stocks '12, '13, so that the 1 half stocks can be turned on the joint pin 14 and opened apart as indicated by the dotted lines in Fig. .3. The preferred means of holding the working chill half molds 1,

. they are respectively secured by the two bolts 21, 22'. which pass through the lialf stocks 1'2, 13, and are furnished with niits 23 on their outer ends so that when these 4 bearing against the tapering sides 18,90, se-

closed while pouring.

are tightened up the heads 24 of the boits curely hold the working chill half molds 1, 2, in the dovetailed recesses. The necessary number of these stocks fitted with the working chill half molds 1, 2, as above described are fixed to the stock frame (see Figs. 1 and For a bedstead rail which has seven upright tubes there are fourteen of these stocks with theircorresponding working chill half molds, seven being fixed to each of the horizontal fiat bars 25, of the stockframes, said stocks being fixed thereto by studs 27 passing through the The other halves 12 of the seven stocks in a row are bolted respectively to the two bars 28, 29, so that all those half stocks in a row will be opened together, each bar being furnished with a handle such as 30, 31, for this purpose. ployed at intervals jointed to the ban-s25, 26, and made with screws 34 to bear upon the bars 28, 29, and maintain the stocks I will now describe the construction of the master chills 'and'the box like part in which they are fixed to form the complete mold when casting the chill working half vmolds 1,). X mold box titted chill for this purpose is illustrated by Figs. 5, ti and 7. This master ('lllll is interchangeal'ile and is made with a part which has in relief the flower 36 or other pattern part or parts which are required to form the recesses in the working chill half molds. The said interchangeable master chills are iron castings made like what is known a platc pattern, that is, with a plate having projecting from itsopposite faces and in exact positions relatively to one another the pattern part 36 corresponding with the recessedpor- Snitableclamps 33, are emtions 37bit the working chill half molds.

The plate part of the master chill 35 is of square or other' coiivenient shape and is adapted to fit in the surrounding mold box sition. Ther mold box is closed -on one face 41 and is made with a recess 42 in the other face in which theisaid plate part of the master chill 35 fits so that the cavity 43 between this plate part 35' and the closed face 41 of the mold box is adapted to receive the molten iron, the ornamental recessed face 37 of which will be formed by the pattern parts- 36 projecting from the interchangeable master chill Before casting the other working chillhalf mold the master chill 35 has to be turned half around and'n'xed with its other face adjacent to' the cavity 43 in the I interior of the mold box. The recess 42 in the mold box ir'r which the master chill 35 is fixed is made with an internal straight edge.

t-land all the master chills-are'made with a corresponding straight edge 45 to correspond therewith and against said internal straight edge 4, the straight edge 4:5 of the master chill is forced by one or more set screws to or other suitable means so that the said master chills are always in their correct positions for casting. The channel I through which the molten metal is poured is denoted by 47. While the above description refers to a mold box for holding a master chill by whicht-he master chill has to be reversed for casting a corresponding pair of working chill half molds, it will be obvioiis that the arrangement may be modified 'as shown in Figs. 13 to 15 in which the mold box 48 is closed on'both faces 49, 50, and the master chill 36 is inserted in the middle of the mold box so as to form two cavities. 51, in which the respective halves of the working chill molds are cast. Two channels 53, 5% areprovided one leading to the cavity 51 and one to the cavity 52- After the master chill 35 has been fixed in the mold box by the set screw 46 the molten metal is poured into the cavity 51 and as soon as the iron is set the mold box complete with the master chill is reversed and the cavity filled through the channel After cooling the two halves of the mold box are ened as shown in dotted lines in Fig. 13

when the master chill and the working chill half molds can be removed.

To insure as aforesaid absolutely sharp or angular edges at the faces of the recessed portions of the working chill half molds 1.

2. the master chili is grooved slightly all around the flower or ornamental or other pattern parts 36 which project from the face located in relation to the half lead pattern .from t of the plate part of the master chill 35 as shown in Figs. 8, 16 and 30, so that when the halves of the working chill molds are cast as aforesaid the molten metal will run into this groove or grooves, and thereby form a rib or ribs 55 (Fig. 3].) projecting up above the faces of the working chill' half molds all around and bordering the recess or recesses therein, as shown to an enlar ed scale in Fig. '33. This rib or ribs 55 an if necessary a part of the face of theworking chill half mold are then removedibyf' gri'nding therebyleaving the edges of the faces of the recess or recesses absolutely'sharp or lar as isnecessary to insure] that the 7 halves as'is usual is molded in sand in a two Inorder to insure that the lead part box. I pattern shall occupy itsproper position in' the said two part box, one half 57 of the said pattern is detachably fixed on a plate 58 by dowel pins 59 or the like, this plate perforated ears through which thapfegs 60 of the one half molding box 61 pass. 'so.- that this half box 61- is exactly 57 see: Fig. 21. lVhen this-part 61 of the box with the half pattern 57 thereinYhas been filled with sand and rammed in the usual waya's shown in Fig. 21', said half box 7 the impression therein is removed e plate 58,'after which the half pattern'57..is lifted off the plate and'replaced in the half mold impression. The other 61 wit:

half 5601' the lead pattern is then'placed onthe other. half molding box 62 is placed on the first half 61 which the first half 57 an 1 1s been molded, as shown in Fig. 24, being 'Inially' filled with sand and rammed. This in its method.- insures' the pattern coming exact required position in the box. I lhe two halvesfl6l, 62, of the molding box are separated? the pattern parts are removed, and between the halves is now introduced the plate 63 which is of thesame thickness as the plate portion of the interchangeable part a master chill 35,.Lthe said plate 63 having an aperturetherethroiigh which corresponds with the outline s'hapeof the master chill mold. The said plate 63 is made with lugs .64 ha ing holes which fit on to the up standing pe s 60 on the bottom box 61, the upper half 2 of the box resting on the upper face of the perforated plate 63. The pegs 60 are by preference made parallel and the half molding boxes are nicely fitted together so that when the top box 62 is placed on the perforated plate 63 the half mold in the too box will be exactly opposite the half an les thereto.

what I claim is parts together at 65 or in any other suitable way. In order to allow for the expansion "of the said intermediate "plate 63 arising L from its contact with the hot metal in' the aperture 66 the holes in the lugs 6i ofthe plate 63 are "so slotted or formed at 67 as to bear upon the outer surfaces 68 of the pegs 60-of the molding box to properly locate the intermediate plate 63 thereon, suflicient clearance being left on the inner sides of the pegs to properly allowfor the expansion of the plate.

In order to make those working chill half molds which are all of thesame pattern but in which the channels for the tubes or bars are in difi'erent angles and positions, as is such for instance as by hinging thetwo required for instance in a bedstead rail in which the toptube is curved instead of being a horizontal straight tube as in Fig. 1, either the lead pattern 56, 57, or the master chill has its print parts 69 for the tubes or bars 6 made at the proper angles or positions to suit the working chill half molds required, as indicated for instance in Fig. 34 1 which shows a-lead pattern like that shown in Fig. 23 but having its two sideprints for the top tube arrangedinclined to the vertical instead as in Fig. 23 being at right aving now fully described and ascertainedmy said invention and the manner in which it isto be performed, I declare that 1.
